AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
337 PM PST SAT DEC 19 2015

.SYNOPSIS...A COLD FRONT WILL APPROACH THE NORTH COAST TONIGHT
BRINGING RAIN AND SNOW TO THE REGION ON SUNDAY. A POTENT RAIN
PRODUCING SYSTEM WILL MOVE THROUGH THE REGION ON MONDAY AND
TUESDAY ASSOCIATED WITH ABUNDANT RAINFALL.

&&

.DISCUSSION...A WEAK WARM FRONT WILL REACH THE NORTH COAST TONIGHT
WITH SOME VERY LIGHT RAIN OR DRIZZLE MAINLY CONFINED TO THE NEAR
COAST ZONES POSSIBLE AFTER MIDNIGHT. THIS WILL RAPIDLY BE FOLLOWED
BY THE ASSOCIATED COLD FRONT SUNDAY MORNING. THIS FRONT WILL MOVE
QUICKLY FROM NORTH TO SOUTH BUT WILL BRING .5 TO 1.5 INCHES OF
RAIN TO THE REGION (POSSIBLE MORE TO RAIN PRONE AREAS) THROUGH
SUNDAY AFTERNOON. SNOW WILL ALSO BE LIKELY AT ELEVATIONS ABOVE
2000 FEET AS COOLER AIR FILTERS OVER NORTHERN ZONES. HAVE ISSUED
A WINTER WEATHER ADVISORY FOR TRINITY COUNTY FOR MAINLY SNOW
IMPACTING ROADS AND HIGHWAYS. VALLEYS ABOVE 2 K FT MAY SEE 2 TO 3
INCHES OF SNOW DURING THE MORNING HOURS BUT SHOULD BEGIN TO TAPER
OFF IN THE AFTERNOON OR CHANGE TO RAIN. FOR ELEVATIONS ABOVE 3 K
FT SNOW SHOULD PERSIST THROUGHOUT THE DAY WITH ACCUMULATIONS OF 4
TO 7 INCHES POSSIBLE. SNOW LEVELS WILL RISE ON MONDAY AS WARM
MOIST AIR AHEAD OF THE NEXT SYTEM MODIFIES THE AIRMASS. THE
RAINFALL ON SUNDAY WILL RESULT IN SATURATED SOILS ACROSS ALL AREAS
ON SUNDAY...WITH LITTLE TIME FOR RIVERS TO FALL BEFORE PERSISTENT
MODERATE RAIN TO HEAVY RAIN ARRIVES ON MONDAY. THERE CONTINUES TO
BE A STRONG THREAT FOR FLOODING ACROSS SOME AREAS WITH PONDING OF
WATER AND FLOODED SMALL STREAMS BY TUESDAY AS ANYWHERE FROM 6 TO
10 INCHES OF RAIN IS ANTICIPATED TO FALL BETWEEN MONDAY AND
TUESDAY. AN AREAL FLOOD WATCH WILL LIKELY TO BE ISSUED TO ADDRESS
THIS TOMORROW...WHILE A SPECIFIC FLOOD WATCH MAY BE WARRANTED FOR
THE VAN DUZEN RIVER AS IT IS STILL PROJECTED TO EXCEED FLOOD STAGE
ON TUESDAY...HOWEVER CONFIDENCE IS STILL LOW WITH THIS OUTCOME SO
WILL HOLD OFF ON THAT FOR NOW. THE BULLSEYE OF PRECIPITATION STILL
LOOKS TO OCCUR OVER DEL NORTE AND HUMBOLDT COUNTIES...HOWEVER
NORTHERN MENDO WILL ALSO SEE A FAIR AMOUNT OF RAIN AS WELL BUT AT
THIS TIME NO SIGNIFICANT FLOODING IS EXPECTED.

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL TONIGHT. LIGHT MIST OR FOG
MAY FORM IN THE UKIAH AREA LATER THIS EVENING AS WINDS GO LIGHT AND
SKIES REMAIN RELATIVELY CLEAR. SOUTHERLY WINDS AND MID TO HIGH LEVEL
CLOUDS WILL BE ON THE INCREASE LATE TONIGHT...WITH LIGHT TO MODERATE
RAIN AND MVFR CONDITIONS EXPECTED AT THE TERMINALS SUNDAY MORNING.

&&

.MARINE...A SERIES OF SYSTEMS WILL IMPACT THE COASTAL WATERS THROUGH
MIDWEEK WITH PERIODIC ELEVATED WINDS AND STEEP SEAS ALL THE WHILE
WEST-NORTHWEST SWELL REMAINS. LIGHT EVENING WINDS WILL TURN
SOUTHERLY AND INCREASE AS A WARM FRONT APPROACHES FROM THE WEST.
GALE FORCE WINDS ARE LIKELY FOR WATERS NORTH OF CAPE MENDOCINO WHILE
POSSIBLE FOR THE WATERS TO THE SOUTH. WE HAVE ISSUED GALE WARNINGS
TO THE NORTH AND WATCHES TO THE SOUTH OF THE CAPE. THESE NEAR GALE
TO GALE CONDITIONS WILL REMAIN THROUGH SUNDAY MORNING FOLLOWED BY A
POST FRONTAL SWELL. ANOTHER FRONT IS FORECAST TO IMPACT THE COASTAL
WATERS ON MONDAY...WITH ANOTHER SHORT LIVED GALE EXPECTED. NWW3
CONTINUES TO INDICATE LARGE NW SWELL ARRIVING WED INTO THU WITH
HEIGHTS UP TO 25 FT WITH PERIODS NEAR 17 SECONDS ON WED. IS THIS
POSSIBLE? ANOTHER 20+ FT SWELL EVENT WITHIN 2 WEEKS OF THE 30 TO 35
FOOTERS WE SAW ON THE 10TH OF THIS MONTH. FOR NOW WILL BEEF UP THE
SWELL FORECAST CLOSE TO THE NWW3 GUIDANCE WHICH HAS BEEN FAIRLY
CONSISTENT. THERE IS STILL UNCERTAINTY ON THE EXACT MAGNITUDE AND
TIMING. ANOTHER HIGH SURF WARNING AND/OR COASTAL FLOOD WARNING WILL
BE NECESSARY IF THE SWELL COMES IN HIGHER. STAY TUNED.

.LONG RANGE (WEDNESDAY THROUGH SATURDAY)...EXPECT COOL...SHOWERY AND
UNSETTLED WEATHER CONDITIONS WITH LOWER SNOW LEVELS MID TO LATE NEXT
WEEK. BOTH THE GFS AND ECMWF WERE SIMILAR WITH A COLD AND MOIST NW
FLOW PATTERN DEVELOPING AS AN UPPER TROUGH DIGS OVER THE AREA WED
INTO THU. THUR OR THUR NIGHT LOOKS PRIME TIME FOR LOW ELEVATION
SNOWS OVER THE MOUNTAIN PASSES. THE ONSHORE FLOW AND LOW TOPPED
CONVECTION WILL ALSO BRING THE POTENTIAL FOR TSTMS AND SMALL HAIL.
FRIDAY IS STILL A BIT IFFY WITH THE ECMWF SLOWER THAN THE GFS WITH
THE EASTWARD PROGRESSION OF THE UPPER TROUGH. SLOWER IS BETTER HERE.
MODELS COME INTO BETTER AGREEMENT WITH SHOWER CHANCES FALLING OFF
MARKEDLY FRIDAY NIGHT AND SAT AS AN OFFSHORE WIND FLOW DEVELOPS NEAR
THE SURFACE. FOR NOW WILL INDICATE DRY BUT COLDER WEATHER
CONDITIONS FRI NIGHT AND SAT.
